t/DOMDocument.t fails

Hi, folks.  I finally managed to build a Xerces.so that doesn't bomb
upon loading via use XML::Xerces.  (I'll give the gory details in the
thread "Building Xerces.so on a Debian system", if anyone is
interested).

So now the only test that fails is t/DOMDocument.t.  Out of 35,125
subtests, 62 of them fail.  The error messages for these 62 failed
subtests all have the same form; for example:

  Error code: 5
  not ok 662
  #     Failed test (t/DOMDocument.t.skip at line 218)
  char: <0x00C0>

Does anyone have any idea of what could be going wrong?

Thanks!
